OPTIMIZATION OF DAM OPERATION FOR MAXIMIZING WATER USE AND FLOOD PREVENTION: A CASE OF ANGAT DAM,PHILIPPINES JARANILLA-SANCHEZ, Patricia Ann SHIBUO, Yoshi KOIKE, Toshio Angat dam is the main domestic water resource for metropolitan Manila. Optimal dam operation is very important in avoiding possible conflicts between different stakeholders who utilize water from the dam. There are 3 main functions of the dam: 1.) for irrigation purposes in the surrounding provinces of Angat (Bulacan and Pampanga province); 2.) for hydropower generation and 3.) for domestic water use in Metro Manila. Conflicts between stakeholders for these three functions are rampant. This study aims to minimize some of the water-related non-political issues that usually arise between stakeholders. There are two main priorities of the dam optimization for Angat: 1.) To maximize water use and 2.) to prevent flood. This study explores different cases of 3 typhoons from 2011 (Pedring, Quiel and Ramon) by utilizing 50% priority on preventing downstream flooding and 50% priority on water use. In addition, the effects of changing the weights of the objective function in the dam optimization for each priority is also determined to identify how the error is minimized in the optimization system. This system can be a useful tool in utilizing ensemble forecasts to minimize the effects of floods in the downstream side while maximizing the storage capacity of upstream reservoirs during dam operation.
